Using Amaya 8.1b on Win2k Advanced Server (also occurred in 8.1a),
1. Create a new XHTML1.1 document.
2. Insert a horizontal rule.
3. Place the insertion point immediately after the rule. (You may have
to do this in Views > Show source)
4. Select XHTML > Table > table
Nothing happens.
If steps 2 and 3 are omitted, then the "how many rows by columns" dialog is
shown as expected.
